car revs hunting at idle HELP
Hello,
I have a little problem with my mercedes w204 220 cdi 2007-2008 , when the car is in IDLE at about 700 revs it start hunting as u will see on the video attached so normally i fell little vibrations, when i turn the ac on it goes like around 900 revs and it stops hunting . so the problem is only at idle with ac off . oil and filters changed and no smoke from the car .and the revs only try to go up and back to 700 nerver down that. what can it be ? i made some digging and it can be the idle air control valve ??, the car dont have any check turned on . someone had this problem ?
thankyou
